Title: Stable liquid catalase compsns. - contg. microbicide as preservative
Inventor: PFEIFFER HANS F DIPL CHEM DR
IPC: C11D3/48
Filed: 1977-12-24
Abstract: Catalase compsn. according to the Parent Patent comprise aq. solns. or suspensions contg. (a) 0.5-10 wt. % anionic surfactant, (b) 2-50% nonionic surfactant and (c) 500-500,000 Iu/ml of catalase, with an (a) : (b) wt. ratio of 1:1-100.

Title: Differential pressure transducer with compensating bellows - uses tube around lever arm to reduce bending due to force compensation
Inventor: WINTER WERNER
IPC: G01L11/00
Filed: 1978-06-20
Abstract: The differential pressure transducer has a membrane (4, 4a) which separates the pressure chambers (6, 8) and is connected to the support (18) of the lever arm (10). The membrane moves under pressure (Pa) towards the lever which moves the deflecting plate (12) towards the nozzle (13). A pressure (PZ) applied through the nozzle detects the nozzle-plate separation to determine the pressure (PA) . Bellows (14) provide force compensation which acts on the tuve (19) surrounding the lever to reduce the required membrane movement. The tube reduces lever bending at large pressures and the membrane displacement is minimized.

Title: Electronic flash for automatic camera - is coupled to transistor circuit to override camera exposure timing
Inventor: WATANABE SAKUJI
IPC: G03B7/16
Filed: 1978-10-27
Abstract: The electronic flash (FL) is used for a photographic camera with an exposure control circuit responsive to the selected exposure, the film sensitivity, the shutter diaphragm setting and the brightness of the subject.
